Getting the date and time stamp of log entries to use rounded microseconds, and how to ensure a log extract uses the current time zone throughout.
LogUI
It turns out that ‘nanosecond’ times introduced in LogUI are largely artefact. Is higher resolution timing really needed, and how can it be obtained?
Although Macs can resolve time to nanoseconds, this isn’t apparent from tests writing log entries very rapidly. This explains what is probably happening.
Although there are important differences between Intel and Apple silicon Macs, both can resolve time to nanoseconds. So can this new version of LogUI.
Actions are moved to its toolbar to improve use. Selected messages can now be extracted into a window for editing (all Macs) and summary using Writing Tools (Apple silicon).
Open multiple windows in LogUI, set them up to obtain the same log extract, then apply different searches to each. A powerful way to read long and complex log extracts.
Search your log extract instantly to show only entries containing the chosen text in their message, process name, sender name, or subsystem.
How to construct and use filter predicates to refine the log entries shown in LogUI or most other log browsers, and in the log command tool.
Adds support for using your own filter predicates so you only see the log entries you want. Either in a one-off editor, or to its popup menu.
This new build checks that it can get log extracts, and has a wider range of filters you can use to select which entries it fetches and displays.
